Description
(54) СПОСОБ ПОЛУЧЕНИЯ ОКРАШЕННОГО ПОЛИМЕРНОГО МЛТЕРИАЛА-ПОЛИМЕТИЛМЕТАКРИЛАТА, ПОЛИСТИГОЛА ИЛИ ПОЛИВИНИЛАЦЕТАТА ;I Изобретение относитс к переработке пласт масс, в частности к способу получени окрашенного полимерного материала - полиметилметакрилата , полистирола или поливинилацетат Известен способ получени окрашенного по лимерного материала - полиметилметакрилата, полистирола или поливинилацетата путем радикальной полимеризации в массе в присутств1Ш жирорастворимого антрахинонового красител шш оксипроизводных ароматических соединений - оксистиролпиридинов 1 . Недостатком данного способа вл етс низка термостойкость окрашенного полимера, на пример полиметилметакрилата, который разлагаетс при 290° С, а также низка светостойкость окраски, интенсивность которой после 5 ч облуче1 ш уменьшаетс в 2 раза. Цель изобретени - повышение термостойкости материала и светостойкости окраски. Указашга цель достигаетс тем, что в качестве красител используют комплексы не фганических солей - хлористого кобальта, уранилнитрата или кислоты форсфорномолибденовой с органическими , выбранными из группы: сульфоксид, трибутилфоофат, диизоамилметилфосфонат, триалкшт- (арил) фосфиноксид или ди-2-эт Шгексилфосфорна кислота , в кошиестве 0,1-2 вес.%. Полученный окрашенный полимер, например полиметилметакрилат, обладает вьтсокой термостойкостью и разлагаетс , при 350°С. Кроме того, интенсивность окраски после 20 ч облучени остаетс прежней. Примеры 1-18..5 кг композиции, состо щей из мономера, жирорастворимого комплекса .и инициатора, вакуумируют, помещают в форму из силикатного стекла и полимеризуют . Мономер, состав комплекса, его содержание, шшциатор и услови полимеризации приведены в таблице. После oKoiniaHHH полимеризашш провод т , допо имеризацию при 120° С в течение 6 ч. Во всех случа х получают прозрачное оптически однород1юе стекло, окрашенное в соответствующий цвет. I р и м е р 19. Композиш1 о. содержа1цую 30 J акрилонитрила, 0,05 вес.% перекиси бен38593914(54); METHOD FOR MAKING A CAMP by radical polymerization in the mass in the presence of 1F fat-soluble anthraquinone dye of hydroxy derivatives of aromatic compounds - hydroxystyrene pyridines 1. The disadvantage of this method is the low temperature resistance of the colored polymer, for example, polymethyl methacrylate, which decomposes at 290 ° C, as well as the low color fastness, the intensity of which after 5 hours of irradiation decreases 2 times. The purpose of the invention is to increase the heat resistance of the material and the light resistance of the color. Ukazashga object is achieved in that the dye is used as the complexes are not fganicheskih salt - cobalt chloride, uranyl nitrate or with organic acids forsfornomolibdenovoy selected from the group of a sulfoxide tributilfoofat, diizoamilmetilfosfonat, trialksht- (aryl) phosphine or di-2-fl Shgeksilfosforna acid, in the amount of 0.1-2 wt.%. The resulting colored polymer, for example, polymethyl methacrylate, is highly heat resistant and decomposes at 350 ° C. In addition, the color intensity after 20 hours of irradiation remains the same. Examples 1-18 ..5 kg of a composition consisting of a monomer, a fat-soluble complex, and an initiator are evacuated, placed in a silicate glass mold and polymerized. The monomer, the composition of the complex, its content, shshtsiator and polymerization conditions are given in the table. After oKoiniaHHH, polymerization is carried out, dopomerization at 120 ° C for 6 hours. In all cases transparent optically homogeneous glass is obtained, painted in the corresponding color.
